:'1-he invention comprises a ba'se 'l supported on feet2, which maybef'positioned in "sockets. 3-formedin abrick-work or other foundation 4as shown in Fig. 9,'and having pedestal-e projecting;vertically upwardtherefrom. Theped'estal is providediwith 1 aqlug .(iyprojecting radiallytherefrom and .inay have; a flat topQas shown; in Figs. 3 and-5, oritma'y {carry an anti-friction roller 7 as shown in'FigVG. The base-isprovided -With ra plurality of equallyspaced, horizontallyjarrangedrollers 8 as shown..

A .frame 9 having acentral opening 10 is positioned. on the pedestal 5and isv rotatable thereon, there being a plurality of slots 10 groupedaround the central opening'in the frame whereby the latter may pass thelug 6. The central portion of the frame is provided with a series ofgrooves ll equal in number to the rollers 8 on the base whereby when thegrooves engage the rollers, as shown in Fig. 9, the frame/is lockedagainst. accidental rotation on the I I ted Apr. 4., 1922. 1 Applicationfiled September 15, 1920.

pedestal, but, by the application of slight force, the grooi'esmay bereleased from the roller. and the frame rotated.

' Radially arranged on the frame 9 is a plurality of rings 12 eachhaving an internal diameter of a size sufficient to receive acylindrical can 13 of solidified alcohol or other fuel, each of which ispreferably provided w th a flame opening of a diameter smaller than thatof the can. A'bar 14 extends across the lower end of each the openingsand 22. 2'5.

ring to support the can. The outer edge of each ring is provided with aseries of axially projecting lugs 15 whereby a can of greaterdiametermay be supported upon the top of the ring and be retained in positionthereon by the lugs. '2

Carried upon the pedestal 5 is a top plate or turntable 16 provided withan elongated hub 17 which engages the pedestal. A portion' 18 'of'theturntable projects over the top'of the pedestal and the weight of theturntable is supported by the engagement of the portion 18' with the topof the pedestal. Api'n 19 projects axially from the pedestal and isadaptedto engage any one of three openings20, 21 or 22 in the portion 18and lock the turntable in any one of three positions and againstrotation.

The hub of the turntable is provided with a groove 23 whereby the hubmay be passed over the'lug 6,'and the upper portion of the grooveiswidened to permlt of rotary movemerit of the'turnta ble to the limitdefined radially extending r'od24 i s fjourn'aled in bearings-on theupper face of the turntable and'isprovided 'atits outer end, at

some distance'from the turntable, with an insulating handle25'. Atitsinner end, and

over the "axial center of' the 'pedestale the 1. rod is rovided with'acam 26 whereby-when the re is rotated the camengaging the top .ofthe"pedestal, or the roller 7 as'the case n y e, 'tach the opening 20,21 or22-from the :pin 19 8 whereby the turntable hring another of saidopenings in alinement 'with'saidpin.

willelevate the turntable and demay be rotated to "The'turntable'16 isprovided with a series .of chimneys 27-corresponding in number 'andinradialand angularlpositlon wlththe rings Y12 and with the cans 13. Thechimneys project above the turntable 'as shown, and in proximity to eachchimney the turntable is provided with a crescent shaped opening 28,

' which openi'ng'is preferably wider at the top than at the bottom asshown. The diameter of the chimney opening plus the widthofthe crescentshaped opening will be "approximately equal the diameter of the flameopening in the can.

The operation is as follows 1- The various parts of the device areassembled as described and the stove is placed upon the hearth or otherfoundation with therod 25 projecting toward the operator, therebeingmeans, such for example as the grid or grill before referred to forsupporting food to be'cooked, positioned above and independentlyof thestove.

The operator will rotate the rod 25 and i the eccentric cam 26 engagingthe top of the pedestalwill elevate theturntable 16 to the positionshown in dotted lines in Fig.

he operator will now place an open can of fuel in or on the ring 12nearest him, and light the fuel therein. He will then rotate the frameone notch and bring the next ring to the frontand place a can thereinand light it. This operation will be continuedluntil each of the ringscontains a lighted can of fuel.

The turntable is now rotated by means ofthe handle until each chimney 27and its adjacent opening 28 come into'axial alinement with each can13,when the rod 25 is rotated, lowering the turntable into contact with thetops of the cans. The pin 19 will enter the opening 20 and the turntablewill .be locked opening,'fthexarea of the opening, and its wedge shapefrom top'tobottom, all serve todirect air downward in quantity to pro" 1erly support combustion in the, can not on y opening partiallyencirclingthe chimney 3 I.

when thesurfaceo'f the fuel is near the top I of the can but as suchsurfacerecedesand' 5 when the last particle of fuel is-in the can, '95

air will be directed to the bottom thereof, and all'of the fuel will beconsumed. I

When it is desired to reduce the intensity of theflame' the rod 25 isrotated and the turntable is raised as, before. The rod is now moved tothe left and the turntable. rotated: until the opening 21 is;po'sitioned-over the pin .19 whenthe turntable is loweredfand 1 theengaging theopening 21 Wlll 'lOCk the turntable against furtherrotaryvmovement. The chimneys and openings 28 are now in positionrelatively-to ithe flame openings in the cans shown :in Fig.2. Thiswillmaterially reduce the size and intensity of the flame but suflicientrairto support combustion will be admitted. 1

When it is desired to extinguishtheflame,

the turntable is again raised, and the handle moved to the left untilthe opening 22 is in alinement with the pin 19. When the turntable islowered'the chimneys and openings 'will be in the position, relativelyto the can flame openings, shown in liig. 10 and, when the turntable islowered by the rotation of the handle, it will rest upon thetops of thecans and'the flames will. be extinguished.

The chimneys are so positioned relatively to the center of the turntablethat the flames will be so concentrated that a large area of the utensilor'other object to be heated will receive the maximum amount of heat,and the source of heat will be sufficiently removed from the operator asto prevent injury or inconvenience to him. I I

The shape of the draught opening 28, and its size and positionrelatively to the chimney,and the proportion of each relatively to theflame opening in the container are of importance. The crescent shape ofthe opening permits-of the greatest size possible and the maximum amountof air may be drawn into the can to support combustlon. By placing theopening to one 'sideofthe chimney the cross sectional area of the flamepassing through the chimney will not be substantially reduced by asurrounding current of cold air moving in the opposite'direction.

effect of an injector, and the column of inrushmg air being reduced 1narea as 1t passes through the opening its; speed will be accelerated andvthespeed; of the inrushing air will be directed wellinto the can andeven to the 7 bottom "thereof when the surface'ofithe burning fuel isatthe lowest level.

'It is -to 'beiunderstood that the invention is not limited touse withsupports and chime i neys for-four cans, but-any desired number 30 maybeemployed. WVhen the occasion requires it the flames of as many of-thecans as. desired may be extinguishedby placing an individual cap orcover on such cans, and

there beingia flameiopening in the receptacle,

the frame 9; may 'be rotated independently ofthe rest of the apparatustobringthecans to; the accessible position.

In .Fig. 12- 'isshown a modification. in

' which there is an extra chimney 27 a and an extra draught opening28%,:situated midway between two of the chimneys 27. When theturntable16 is turned to the position corre- 'sponding to Fig. 10, the flamesof'all of the cans butone will be extinguished, and the flame of thesingle can will be suflicient to keep the utensil above the stove warm.hen it is desired to extinguish all-of the flames a cap or cover may beplaced over the can beneath the chimney 27 by slightly raising theturntable. i

In accordance with the provisions of the patent statutes the principleof the invention, together with what is now considered. to be thebest'embodiment thereof, have been described, but it is to be understoodthat the apparatus'described is merely illustrative, and that theinvention maybe carried out in other ways.
